Date: 2001-11-14
The temperature&humidity transmitter, HMP233, weretested at +22...+90 'C.
Test station
The test station is based on humidity generators anda temperature test chamber. The gas from thehumidity generators, Thunder Scientific model 2500or model 3900, is led into the measurement chamber.The temperature of the measurement chamber ischanged by the temperature test chamber, VbtschVT7004. The reference humidity value is calculatedfrom Thunders dew point value and the temperature ofthe measurement chamber.

Date: 2003-02-19
The transmitter HMP233 was tested at temperatures+120..+180'C.
Test station 2.
A test station for high dew point values: The teststation is based on a saturator unit and a measurementchamber placed in oven. The temperature of thesaturator (dew point) is controlled by a liquidthermostat (Lauda RC 25 CP). The saturated gas from thesaturator is led into the measurement chamber via heatexchanger. The temperature of the measurement chamberis changed by the oven (Heraeus UT 6120). The referencedew point value is calculated from the temperature andpressure readings of the saturator and the pressure ofthe measurement chamber. The reference humidity is thencalculated using the dew point temperature and themesurement chamber temperature.

Test station 1.
The test station is based on humidity generators anda temperature test chamber. The gas from thehumidity generators, Thunder Scientific model 2500or model 3900, is led into the measurement chamber.Nitrogen gas is used as dry point (0%rh) attemperature above 0'C. The temperature of themeasurement chamber is changed by the temperaturetest chamber, Vbtsch VT7004. The reference humidityvalue is calculated from Thunders dew point valueand the temperature of the measurement chamber.
